He is the leader of the babies, and is dressed in a blue shirt and diapers throughout the series (with the exception of the first episode in which he wears an orange shirt). He is best friends with Chuckie Finster. Tommy is also the bravest and most adventurous of all the babies. He is also willing to do whatever he has to for his friends and family.[1]

Charles "Chuckie" Finster, Jr. (voiced by Christine Cavanaugh up to 2002; Nancy Cartwright to series' end): Chuckie is the oldest of the babies at the age of 2 and is Tommy's best friend. He is the son of Charles "Chas" Finster and his late mother's name was Melinda.[2] He has messy orange hair, wears large purple glasses like his father, and wears a blue shirt with the planet Saturn on it and green cargo pants and red shoes that are always untied. Chuckie was originally an only child and his mother died from an unknown reason just a few months after Chuckie was born. He is the scaredy-cat of the group and always disapproves of an adventure that comes up. Later on, his father remarries Kira and Chuckie becomes an adopted big brother to her daughter, Kimi. Kira adopted Chuckie. He and his father, Chas, are the main characters of the film, Rugrats in Paris. His middle name is Crandall as proven in the episode "Chuckie Loses His Glasses" and All Grown Up! episode, "Rat Traps".[3]

Phillip "Phil" and Lillian "Lil" DeVille (Both voiced by Kath Soucie): Twins (boy and girl, respectively) Phil and Lil are the twin children of Howard and Betty DeVille. They enjoy doing everything together, whether it be playing in the mud or finding insects. They are often confused due to their similar appearance, despite the fact that Lil has a long one piece dress over her diaper that matches Phil's shirt over his shorts (green with a duck on it) and has a bow in her hair to tell them apart. They usually call each other by their full first name (Phillip and Lillian) whenever they argue.[4][5]

Angelica Pickles (voiced by Cheryl Chase): Angelica is Tommy and Dil's cousin and daughter of Drew and Charlotte Pickles. She is very spoiled by her mother and father and mean to the babies, but will occasionally do something nice for them. She has short blond hair tied in two pigtails with purple bows, a purple dress with a red undershirt and polka dot stockings. She is able to speak with and understand both the babies and adults.[6]

Susie Carmichael (voiced by Cree Summer, with E.G. Daily filling in for a couple of episodes[7]): Another child capable of talking to both the adults and the babies, Susie often serves as Angelica's rival and bullying foil, but the two are actually really close friends. She is kind, compassionate and trusting. She often wears a bright colored jumper and shoes similar to Angelica's outfit. Carmichael is African-American (the only one of the core Rugrats of that ethnicity) and was added to the series during the second season (episode "Meet the Carmichaels"). Despite being a major character, she appeared less frequently than the other Rugrats.[8]

Dylan "Dil" Pickles (voiced by Tara Strong): Dil is Tommy's younger brother. He is unable to speak to the babies, but is able to garble words together. He likes to chew and drool on people and things. He also enjoys hitting Tommy in the head with various objects, most notably his rattle. Dil was introduced in the first Rugrats movie after his birth. At first, Tommy and Dil are extremely jealous of each other, but the two later realize the bond they share as brothers. He is named after his mom's cousin short for Dylan.[9]

Kimi Finster (voiced by Dionne Quan): Chuckie's stepsister, introduced in the second Rugrats movie, Rugrats in Paris. Kimi, the group's sole Asian character, is of Japanese descent; she is a very adventurous girl, much like Tommy, and always maintains a positive attitude and a bright smile. She helps Chuckie learn to be a good big brother and often helps him overcome his fears.[10]

Spike (voiced by Michael Bell in a dream sequence in the episode "In the Dreamtime"; Bruce Willis in Rugrats Go Wild): The Pickles' family dog. Though he appears in almost every episode of the series, he is not usually featured as a main part of episodes. Tommy claims him to be his best "animal" friend. The character is considered a main character in the series, appearing in almost three quarters of all of the episodes, though he usually does not come along when the Rugrats venture to new locations. It is mentioned that his breed is the fictional "Siberian Tiger Hound." As shown in The Rugrats Movie and Rugrats Go Wild, Spike is very protective of the babies, as he sees them as his own.

He is feared by both the babies and the monkeys; in the climax of the film, he tries to attack the babies after scaring the monkeys away, but is defeated by Spike, the Pickles' dog.

Her boss is offering her the job for president of the company, but only if she learns to love children, to which she lies about and says that she is engaged. This sets the climax for the film. The real reason she brought the Pickles and gang to France is so that Stu could fix Robo Reptar. She also plans to kidnap the babies because she hates kids; when her plans got discovered, her wedding gets called off and her boss fires her, much to her humiliation. Angelica steps on her wedding dress, causing it to rip to have her underwear shown in front of everyone, including some people with cameras.

Jean-Claude (voiced by John Lithgow): Coco's close assistant. He is loyal to his boss and helps her with the kidnapping of the babies. He usually has the job of telling Kira what to do.
